java - log4j.properties 被忽略

Question

我在 glassfish v3.0.1 上使用 IntelliJ IDEA 9.0.3 通过 maven 部署了一个 Java EE 6 Wicket 应用程序。我将 slf4j-log4j12-1.5.6 与 slf4j-api-1.5.8 和 log4j-1.2.16 一起用于日志记录。

当我通过 netbeans 或 eclipse 部署时，它以前工作正常，但是当我使用 IntelliJ IDEA 部署时，我的 log4j.properties 文件被忽略，glassfish 的日志记录处理我的日志消息。我不认为 IDEA 与它有任何关系，一定有其他东西改变了我只是想不通是什么。

我已验证我的 log4j.properties 文件在我的 WEB-INF/classes 目录中，slf4j/log4j jar 文件在我的 war 的 WEB-INF/lib 目录中。是否缺少某种配置来使这项工作正常进行？

谢谢。

编辑:更新了更多信息，发布了 pom 依赖项。

这是我的 pom.xml 中的相关部分:

Answer 1

更新:我尝试重现该问题。我创建了一个简单的 Wicket 项目(与您的版本相同):

mvn archetype:create \
-DarchetypeGroupId=org.apache.wicket \
-DarchetypeArtifactId=wicket-archetype-quickstart \
-DarchetypeVersion=1.4.9 \
-DgroupId=com.mycompany \
-DartifactId=my-wicketapp 

其中有一个简单的 log4j.properties 记录到标准输出。

log4j.appender.Stdout=org.apache.log4j.ConsoleAppender
log4j.appender.Stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.Stdout.layout.conversionPattern=%-5p - %-26.26c{1} - %m\n

log4j.rootLogger=INFO,Stdout

log4j.logger.org.apache.wicket=INFO
log4j.logger.org.apache.wicket.protocol.http.HttpSessionStore=INFO
log4j.logger.org.apache.wicket.version=INFO
log4j.logger.org.apache.wicket.RequestCycle=INFO

然后:

• 我添加了您所有的依赖项(或修改了现有版本以匹配您的依赖项)
  • 我刚刚做了一些清理工作，例如在 Hibernate 依赖中，你不需要全部声明它们，利用传递依赖机制
• 我添加了相关的repositories 和pluginRepositories
• 我添加了 glassfish 的 javax.servlet 依赖项以使构建通过
• 我添加了 embedded-glassfish 插件来测试整个事情
• 我做了一些其他不相关的更改
  • 我将编译器设置更改为 1.6
  • 我在 dependencyManagement 元素中声明了 slf4j-api 以很好地控制传递依赖项中的版本。

当我使用 embedded-glassfish 插件运行项目时:

$ mvn package...$ mvn embedded-glassfish:run...

并访问http://localhost:8080/server在浏览器中，我按预期在标准输出中获取日志:

...INFO: [WicketApplication] Started Wicket version 1.4.9 in development mode*********************************************************************** WARNING: Wicket is running in DEVELOPMENT mode.              ******                               ^^^^^^^^^^^                    ****** Do NOT deploy to your live server(s) without changing this.  ****** See Application#getConfigurationType() for more information. ***********************************************************************

不知道这个有没有代表性

I have checked the war, log4j.properties is indeed in WEB-INF/classes. I don't have a log4j.jar, i have slf4j-log4j12.jar.

slf4j-log4j12.jar 不是 log4j.jar 的替代品，slf4j-log4j12.jar 是 log4J 1.2 版的绑定(bind)，您仍然需要 log4j.jar。来自 SLF4J 文档:

Binding with a logging framework at deployment time

As mentioned previously, SLF4J supports various logging frameworks. The SLF4J distribution ships with several jar files referred to as "SLF4J bindings", with each binding corresponding to a supported framework.

slf4j-log4j12-1.6.1.jar: Binding for log4j version 1.2, a widely used logging framework. You also need to place log4j.jar on your class path.

我想知道您是如何在 NetBeans 和 Eclipse 下运行它的。
